I agree with the other raters; this is a little short, but it's not too tight (as a rash guard is supposed to be tight) Seems true to size, will work just fine for my daughter. Material is a little thicker and will last a little longer; an added plus.

Got this for my daughter, who likes to be well covered while swimming (board shorts & rash guard shirts). She's normally a medium, but a large in this shirt fit just fine. The high neck is snug & makes the shirt a bit difficult to pull on, but the materials are good. The shirt's a little on the short side - a couple more inches would be perfect - but it works well enough.
